Definitions

  • a power electronic device is orientated to miniaturization, lightweight, high efficiency, and low cost.
  • a power semiconductor device is in a hard switching operation state, and there is a larger overlapping area between voltage and current, causing problems such as large switch loss, electromagnetic interference noise, ringing and the like, thus resulting in high cost, huge volume and low efficiency of the systems. If high performance is desired to be available, high cost is needed.
  • the semiconductor industry has developed rapidly, but high-performance devices have not yet been used in large scale, so the study on soft switching circuit topology is still a selection for most of power supply manufactures to improve product competitiveness.
  • US 2011/109162 has disclosed a converter to supply an AC voltage and current from three DC voltages comprising two switching units provided with first switching means connected between an input and a switching output, said converter comprising, for each switching unit, second switching means connected between said switching unit and a modulated signal output, and a switching aid circuit, said converter comprising control means acting on the second switching means associated with the switching unit that is connected to the voltage input of opposite sign to the sign of said AC voltage to establish turn-off of said second switching means when said AC voltage and said AC current are of opposite signs.
  • An uninterruptible power supply comprising the converter described above.
  • the present invention provides a control method according to claim 1 and a device according to claim 6 for a circuit with a bridge arm of a switch, so as to reduce system loss and noise, thus improving efficiency.
  • the invention is defined by a method according to claim 1 and by a device according to claim 6.
  • Advantageous aspects of the invention are defined in the dependent claims.
  • step S1 at a time when current is completely transferred from a main switch circuit comprising the at least two bridge arms of the switch in the circuit to an auxiliary switch circuit comprising the auxiliary switch in the circuit, the main switches set at the same position of individual bridge arms of the switch are controlled to be simultaneously turned on; in the step S2, at a time when current is completely transferred from the auxiliary switch circuit to the main switch circuit, the auxiliary switch is turned off.
  • the magnitude of ⁇ t1 and ⁇ t2 depends on resonance energy, operating frequency, and switching speed.
